Probability of contracting a sexually transmitted infection (STI)


Hello, doctor! I am a male.
I previously engaged in sexual activities with a friend and would like to know the likelihood of contracting a sexually transmitted infection (STI) in this situation (this was my first sexual experience).
During the encounter, I used a condom for both oral and vaginal intercourse from the beginning.
At one point, I changed the condom because my partner thought I had ejaculated, but I informed her that I had not, so we put on a new condom and continued.
Both condoms remained intact throughout the process.
At the end, she removed the condom and manually stimulated me to ejaculation.
What is the risk of her hands coming into contact with my genitalia and transmitting an infection?
1.
During the sexual activity, I inserted my fingers into her vagina and also engaged in oral stimulation of her breasts.
Is there a risk of contracting an STI from these actions?
2.
After the encounter, I used wet wipes and toilet paper to clean myself and washed my hands immediately.
Is there a risk of infecting other areas of my body?
3.
If I were to unfortunately contract an STI, should I consult a urologist?
I apologize for the many questions and appreciate your understanding.
Thank you!

Hello:
1.
From the beginning, I used condoms for oral and vaginal intercourse (I changed the condom midway because my partner thought I had ejaculated, so we stopped to remove it; later, I told her I hadn't ejaculated, and we put on a new one to continue.
However, there were no issues with the condom slipping off, and it was fully on the penis both times).
At the end, she removed it and helped me finish manually.
What is the risk of her hands coming into contact with my genitals and potentially transmitting an infection? — There is a possibility of transmission whenever there is contact with bodily fluids.
According to the risk levels associated with sexual activities, the safest methods include masturbation, hugging, and touching areas other than the genitals; low-risk activities include mutual masturbation, light kissing, mutual rubbing, and condom-protected intercourse; moderate-risk activities include deep kissing, oral sex, and withdrawal before ejaculation; high-risk activities include unprotected intercourse and intercourse that causes wounds or bleeding.
2.
During the sexual activity, I inserted my fingers into her vagina and also sucked and licked her breasts.
Is there a risk of contracting a sexually transmitted infection (STI)? — Refer to the above.
3.
Afterward, I used wet wipes and tissue to clean myself and immediately washed my hands.
Is there a risk of infecting other parts of my body? — This should reduce the risk.
4.
If I unfortunately contract an infection, should I see a urologist? — You can see a urologist if you have symptoms, provided that your partner has a sexually transmitted infection.
Wishing you good health.

When it comes to understanding the risks of sexually transmitted diseases (STDs) after your first sexual encounter, especially in the context of engaging with sex workers, several factors need to be considered. Let's break down your concerns systematically.

1. Condom Use: You mentioned that you used condoms throughout the sexual encounter, including during oral and vaginal sex. This is a critical factor because when used correctly, condoms significantly reduce the risk of transmitting STDs, including HIV. The fact that you changed condoms when necessary and ensured they were properly fitted is a positive aspect. If the condoms did not break or slip off, the risk of transmission from vaginal intercourse is considerably lower. However, it is important to note that while condoms are highly effective, they are not 100% foolproof.
2. Hand-to-Genital Contact: You expressed concern about the risk of infection from your partner's hands touching your genitals after they had been in contact with their own body. The risk of STD transmission through hand contact is generally low, especially if there are no visible cuts or sores on the hands. However, if there were any bodily fluids on the hands and they came into contact with mucous membranes (like the urethra), there could be a slight risk.
3. Oral and Manual Stimulation: You also mentioned that you engaged in manual stimulation and oral contact with your partner's body. While oral sex does carry some risk for STDs, the risk is lower compared to vaginal or anal intercourse, especially if no ejaculation occurred in the mouth. However, if your partner had any oral infections or sores, this could increase the risk.
4. Post-Encounter Hygiene: After the encounter, you took steps to clean yourself with wet wipes and washed your hands. This is a good practice as it helps reduce the risk of transferring any potential pathogens to other areas of your body. Washing your hands immediately after sexual activity is crucial, especially if you have touched any bodily fluids.

5. Symptoms and Testing: If you experience any symptoms such as unusual discharge, sores, or discomfort, it is essential to seek medical attention promptly. Even in the absence of symptoms, it is advisable to get tested for STDs after engaging in sexual activities, especially with new partners. The Centers for Disease Control and Prevention (CDC) recommends routine screening for sexually active individuals, particularly those with multiple partners or those who engage in high-risk behaviors.

6. Consulting a Specialist: If you are concerned about potential exposure to STDs, visiting a urologist or a healthcare provider specializing in sexual health is a wise decision. They can provide you with appropriate tests and guidance based on your specific situation.
In summary, while the use of condoms greatly reduces the risk of STDs, there are still factors to consider, such as the potential for transmission through hand contact and oral sex. Maintaining good hygiene practices post-encounter is beneficial, and if you have any concerns or symptoms, seeking medical advice is crucial. Regular testing is also an essential part of maintaining sexual health, especially after engaging in sexual activities with new partners.
